Both approaches accomplish the same thing — raising the upper body above the level of the stomach — but they do it differently, and the right choice usually comes down to comfort and sleeping style. A wedge pillow sits under the upper body and creates an incline directly at the mattress surface; it's easy to try, portable, and doesn't require modifying the bed frame, but it can shift during the night and some people find the angle less comfortable for side sleeping. Bed risers lift the entire head of the bed frame, creating a gentler, more gradual incline across the whole mattress; this tends to feel more natural for people who move around during sleep, but it requires a compatible bed frame and affects anyone sharing the bed. Neither is objectively better — a wedge is the easier first thing to try, while risers are worth considering if a wedge feels unstable or uncomfortable over time.
